You may find that a valuable source of information in Brazil is Dr. Mario Maranhao in Curitiba. Dr. Maranhao has been the president of the World Union of Cardiologists and has worked with Dr. Dean Ornish.Like myself, Dr. Maranhao has personally experienced heart disease and has changed his lifestyle to reverse it.

If you need his email address, please send me a personal email and I'll send it to you.

As far as other references, you can find them in my book. The book is available online, but the references are not in the online edition. The cheapest way to get those is a used copy on amazon.com.
